P263C: Glow Plug Control Driver Performance
Standardized SAE J2012 code · P26xx — Computer and output circuits
What does P263C mean?
The glow plug control driver does not respond to commands within tolerance. Cold-start glow function is degraded so cold starting can be delayed and white smoke increases.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Symptoms
- Glow plug warning light on (often orange coil symbol)
- Hard cold start or no start in cold weather
- White smoke from exhaust during warm-up
Common causes
- High Aged driver shows degraded switching behaviour
- Medium Current feedback loop noisy
